COIN-CONTROLLED LIFTiNG-MACHINE.

SPECIFICATION fOlmn-g part Of Letters Patent NO.y 397,229, dated February 5, 1889.

Application filed March 22, 1888. Serial No. 268,157. (No modeld To all whom it may concern:

Bc it known -that l', BERNHARD l? CHTER, ot' Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Lifting-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exa-ct description.

rlhis invention relates to an improvement in lifting-machines; audit consists in certain peculiarities of the construction 'and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe its construction and operation, referring' to the accompanying drawings, in which- Figure l is a front elevation of my device. Fig. 2 is a vertical transverse section of the machine, taken behind the dial-plate and showingl` the mechanism for operating the hands. Fig. IS is a rear view with the back plate or cover of the casing removed to show the locking-dogs and t-hc coin-chntes. Fig. 4E is an enlarged view of the locking-dogs, showing a coin in position between their ends and the dogs in the act ot' releasing the liftingslide. Fig. 5 is a similar view with the coin shown in dotted lines and with the dogs in their locking position. Fig. G an enlarged vertical section taken on line (j (i of Fig. 3, and Fig. 7 is an enlarged detached isometric view of the lifting-bar provided with studs which engage in notches on the locking-dogs.

c represents a main frame, cast or formed of any suitable material, and covered by a casing of any material, preferably of sheet metal, and made in any ornamental form to render the machine attractive, as will be clearly understood without further description herein. The frame a has formed across its inside a pair of cross-bars, b, and a pair of tubes, b, secured to the top of the frame, are passed through the upper cross-bar, as clearly seen in Fig. 2, to act as guides and sockets for a pair of vertically-sliding rods h2, which i slide in these gu1de-tubes, and through the lower cross-bar, as clearly shown. Upon the sliding rods l. place the tension-springs O, against which the operator exerts his strength, these springs having one end connected to i the sliding rods and the other bearing against the lower ends ol' thc guide-tubes and acting always against the upward movement of the rods.

To a bar, C', coni'iecting the rods b2 near their lower ends, l secure a li fting-bar, d, also sliding through the centcrof the upper crossbar, I), of the frame, and having its upper end formed with a screw, d', upon which is screwed the hollow extension d?, passed out through the top of the machine, and provided or formed with three hand-holds, (Z3-a central one and one upon each side-in order that the test of lifting-power maybe made with either one or both hands without twisting or binding the sliding parts by friction. The object of connecting the lifting-bar and its handleextension by screw-threads is to render the handle readily adj ust-able as to height, and so permit persons of different sizes to start the lift-test fairly, and from a point that does not prevent their proper exertion of such power as they may possess.

The face of the mach inc is provided with a dial-plate, c, having a scale-ring marked around it to indicate the number of pounds that are lifted, and a small spindle, e', passed through the diametric center of the dial, is provided on its outer en d with a short arm, e2, having its end bent over or hooked, for a purpose presently made plain. Upon the inner end of the spindle e is a small spur-pinion, y", which is engaged and operated by a rackbar, f', on the lifting-lntr, to move the spindle and its bent arm in exact accordance with the movement of the lifting-bar, when the power is applied.

Upon the outside the dial-plate is protected by a glass plate, g, in the center of which is pivoted an indicator-hand, g', which is en` gaged and moved around the dial by the bent arm c2 on the spindle e and marks the amount lifted upon the dial. As the arm e2 and indicator-hand g are not connected, but one only pushes the other around, it will be seen that when the lifting strain is released and the sliding parts and the arm e? return to their normal position the indicator-hand is left to mark the amount lifted, till it is turned back by means of a button, g2, upon the outside of the glass, and which is connected with the hand for that purpose.

IOO

This machine belongs to the class that are placed in publie places, and which are normally locked against any movement, but which are unlocked for a single operation by 5 the insertion of some stated coin,and for this reason a lock must be provided to prevent operation of the machine except when the predetermined coin is inserted. I construct this as follows:

Upon a plate, P, secured to the cross-bars 7) of the main frame in the rear part of the machine, are pivoted a pair of dogs, 7l, provided with springs 7H, acting to press their upper ends together, as clearly seen in Figs. i i 5 and 5. The llower ends of these spring-d ogs are formed on their outer edges, with the notches 712, having the inclines 71,3 extent'ling each way therefrom, and a parir of studs, 7., secured on the slidiiig lifting-bar and projectzo ing through slots 7," in the plate P, are en gaged b v these notches to lock the machine against any lifting movement. 'lhc studs 7u, as best shown in Figs. if and 7, are preferably formed or secured on a yoke-shaped cross-bar, 2 5 l, at right angles thereto, and of su eh a length that when the cross-bar 'B is attached to the side of the lifting-bars (7 the studs 7.: will project `through slots 7," in the plate I), Fig. (5, and normally engage with the dogs 71y at'a 3o point on the lower inclines, 7e", when the draww bar C7 is in the position shown in Fig. A coin-chute, fm, is provided passing down through the top of the machine and terminatin ,just above the spring lockingdogs, and 3 5 the inner edges of these dogs, near their upper ends, are eut out, as at in', to fit the periphery of any particular coin that may be selected as the price of one operation of the machine. .Iustbelow this point a second chute, 4o m2, receives the coin when it is .released by the dogs and conducts it down to a suitable box or receiver below or inthe base of the machine, and from which all the money collected is removed at pleasure by the owner of the machine. The coin /i slides down the chute m and lodges in the cut-out Am atthe upper extremity of the dogs 71, and as the lifting-bar is raised the springs 7i are unable to rock the dogs 7i on their pivots asuiiicient distance 5o to force out their lower extremities, owing to the obstruction caused by the coin to their movement; hence the notches 71,2 do not. engage with the studs 7i, and thus prevent the upward movement of the lifting-bar. On the contrary, if no coin has been inserted there is nothing to obstruct the movement of the upper ends of the dogs 71, and consequently when the bar d begins to rise the studs fasteued thereto on the crossbar B ride up the 6o lower incline of the notches 7i`- and the springs 71,' rock the dogs inward on their pivots, thus carrying' the notches 7i,2 outward sufficiently to engage the studs 7u and prevent the farther movement of the lifting-bar.

It will be noted that when the draw-bar d is entirely down to its normal position, as shown in Fig. 3, the studs 7i' bear against the 7L, far enough to open the opposite end to reeeive the coin in the cut-out on', and should the handles d3 be pulled without payment, as the lugs 7e are drawn up, thereby allowing the spring 7L to act, the notched dogs at once engage the studs 7.; and lock the machine against farther movement; but if a proper coin is first dropped into the chute it falls into the eut-out m between the upper jaws of the dogs, thereby locking the dogs against the action ot' the springs 7i", and then when power is applied the studs 7.'y are drawn by the har (.7 above the locking-notches and strike the upper inclines, thus forcing the lower ends of the dogs together, releasing the coin to fall into its receiver, and leaving the operator free to pull the lift-bar out as far as his strength will permit, the full amount in pounds being registered by the in dicator-hand on the graduated dial, as previou sly explained. T he operation of the whole device will now be clearly understood and its simplicity and economy of construction appreciated.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is"

l. In a test-lift machine, the combination, with the lifting-bar provided with lockingstuds and a coin-chute, of a pair of spring actuated locking-dogs pivoted below the end of the coin-chute and provided in' their upper ends with a curved seat for the coin, and having their lower ends notched and formed with inclines both above and below the notches, substantially as and for thepurpose set forth.

i. In a test-lifting machine, the combination, with the lift-bar and its springs, the bar being formed with locking-studs and provided with a rack-bar, and an adjustable l1andhold, the indicator-hand, the graduated dialplate, and the connecting-spindle between the indicator-hand and the lift-bar provided with a pinion and a bent arm, of a coinchutc for delivering the coin to the locking-dogs, a pair of spring-actu ated lookin g-dogs engaging the lift-bar at one end and formed to receive the coin in their other end, and a second coin-chute for delivering the coin to the receiver, all constructed and arranged to operate substantially as and for the purpose set forth.

In testimony whereof I have here unto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of 0nondaga, in the State of New York, this 13th day of Alia-rch, IESS.
